Added rough draft of the Robottelo code standards

This is the initial draft of the Robottelo Code Standards.
I have created the format and some basic guidelines and background.
However, it will be up to the other members of the team to fill in
items that they feel are important.

This addresses #1496 
yeah, this is basically straight from PEP8 and some other resources. Again, not really a huge deal, but could be something we get into.
